USB Power Controller
General Description
The MIC2010 is a dual channel USB power switch designed
to support the power distribution requirements for USB
Wakeup from the ACPI S3 state. The MIC2010 will directly
switch its two outputs between a 5V main supply and a
5V auxiliary supply normally provided in ATX style power
supplies.
The MIC2010 will adjust its current-limit threshold according
to the ACPI state it is in. In the normal active ACPI S0 state
the current-limit is set at 500mA minimum per channel
satisfying the USB continuous output current specification.
In the S3 state the current-limit can be reduced to a value
determined by an external resistor to minimize the current
that is supplied by the auxiliary supply, thereby ensuring that
voltage regulation is maintained even during fault conditions.
The MIC2010 provides make-before-break switching to
ensure glitch-free transitions between the S3 and S0 states.
Each channel is also thermally isolated from the other so that
a fault in one channel does not effect the other. FAULT status
output signals are also provided indicating overcurrent and
thermal shutdown conditions.
The MIC2070 option latches the output off upon detecting an
overcurrent condition lasting for more than 5ms minimum.
The output can be reset by either toggling the EN inputs of the
MIC2070-1/-2 or by removing the load. Latching the output
off provides a circuit breaker mode of operation which
reduces power consumption during fault conditions.
